None of them are particularly my style, but Evanthe seems the most wearable to me.Astoria has a couple of cute nicknames to go with it, but it does start with the Ass sound, which puts me off it a bit.
Dreama just looks like a creative spelling of the word dreamer to me, I don't know if it's a legit name or not but it looks made up; Violante also looks a bit made up, like Violet (which is a name I'm not all that keen on) wasn't good enough, and also I wouldn't know how to pronounce it - is it meant to be said like the word violent or with the -e pronounced, like vio-lan-tuh?
Dahl to me is a surname, I was a big fan of the author Roald Dahl as a kid so that's my association with it.Brunhilde would probably be my second option, as it's a legit girls' name, though it reminds me of a German grandmother. Maybe better as a middle, something like EvantheBrunhilde?

Thank you for the insight, definitely helpful Evanthe seems to be a lot of people's favourite!

Evanthe is the stand-out for me, although to be honest I'm not keen on any of them. It's a nice alternative to Anthea. Astoria comes in second, it has a nice ring to it and has nice diminutives. Personally I would pronounce it uh-story-a, besides being how I would naturally think to pronounce it, it also removes the 'ass' connection, although I could still see people pronouncing it ASS-story-a, think of the teasing!
Dreama looks like you have phonetically spelt dreamer in my native Aussie, and in Aus would probably be associated with the worst kind of Bogans. I don't know if it is a legit name, but if I were to go this route I would go with Dreamer anyway.
Dahl, if not a surname to me feels like a boys name. Brunhilde screams old lady to me, but would be a nice enough second or middle name. Violante, even with the e pronounced I can just imagine every man and his dog would call my child 'violent' which makes this a no-go. Also, it doesn't matter that I'm not French, it's meaning would still put me off.
